IMPROVEMENT IN soLDERlNG-MACHINES.

Specification forming part of Letters Patent No. 137,888, dated April15, 1873 application filed January 17, 1873.

To all whom it may concern:

Be it known that I, WILLIAM D. BROOKS, of Baltimore, in the county ofBaltimore and State of Maryland, have invented a new and usefulImprovement in Soldering-Machines for Making Pipes and Cans; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing forming apart of this specication.

The invention consists in the improvement of machines for soldering cansor pipes, as hereinafter described and subsequently claimed.

The drawing represents a front elevation of my improved machine.

In the drawing, A. represents a frame made of suitable material andprovided with the hollow cylinder B, attached thereto by a neck, a. Thecylinder or can-holder Bis made of thin metal, apertured on top, anddisconnected from frame as much as possible, so as to prevent anunnecessary absorption of heat, and to require but little for raisingits own temperature, preparatory to receiving the sheet, which isintended to form the can-body. C is the clamp, made almost in the shapeof a knife-blade, pivoted in its shank to the upright D, and restingwith its handle upon a spring, E, that surrounds a post, F, passingthrough a vertical hole in said handle. By this construction the springholds the clamp down upon the can-body, which has been slipped over orabout the cylinder B, while it is readily forced therefrom by a pressureof thefoot, or any other agency, upon the end of handle. incloses asuitable waterchamber at the top, airchamber in the middle, andgaschamber below. The two latter, respectively, have internal andsurrounding` pendent pipes g g, which form the burners. The pipes H I,respectively, connect with the gas and air-chambers and-feed the pipes gg1,`while an airpipe, J, passes around and has its outlet just above thetop of cylinder B, for the purpose of cooling the soldered seam quicklyand effectively. K is an air-pipe connecting with a blower, bellows, orair-forcingpump at one end, while at the other it is attached to the Grepresents the casing, which threeway cock L that connects the twoairpipes I J. By this arrangement of pipes, in connection with theair-supply pipe K and three-way cock L, the incoming current of air maybe readily turned into either direction, while the other is shut off.The effect is that, when the gas-cock and the threeway cock of theair-pipe are moved so as to bring the thumb-pieces of cocks in ahorizontal plane, and to throw the current into the pipe I, the burnersare supplied with oxygen in proper quantity, and freely impinge theflame upon the seam, along which the powdered resin has been alreadythrown and the wire solder is then passing. When, however, the thumb-pieces of cocks have been brought into a perpendicular position, thesupply of air and gas is cut off, While the cold air is forced ythroughpipe J and along the soldered seam,

so as to cool it thoroughly and rapidly. It is very desirable that thisshould all be done by a single and simple movement of the operator, andalso that a small supplyl of gas should be rendered possible, so thatthe burners may not entirely go out when unnecessary to act upon thesolder. My means for accomplishing this consist of the crooked sin gleAslotted bar M, the double-slotted bar N, reA spectively attached to thethumb-pieces of the air and gas-cocks, and the hand-slide O, movable ina guide, I. By this mechanism, when the slide O is pushed out to itsfurthest extent the burners ,are reduced to a feeble flame, which iscaused by a filing across the gas-outlet so as to allow a small leakage.When reversed, a full blast for impinging a hot ame upon the seam ofcan=body is created. In the first instance the air is shut oft` entirelyfrom the burners and forced through pipe J and upon the seam ofcan-body, while in the second it all passes into the pipe I.

, One or more of pipes g may be Iitted with a plug, g2, as shown in thedrawing, for the purpose of allowing cans of greater or less length tobe soldered.

Having thus described myinventiomwhatl claim as new, and desire tosecure by Letters Patent, is-

1. The hollow cylinder B, connected with the frame A by a smallintermediate neck, a, and in contact therewith at no other point, asdescribed, so that a minimum of the heat which the former receives fromthe blow-pipes Will be lost by. transmission to the latter.

2. The coinbinatiom'with cylinder B that holds the can-body Which isbeing soldered, of an air-pipe, J, arranged horizontally to force acurrent of cold air across the soldered seam of can, as and forv thepurpose specified.

3. The can-holding` cylinder B, slotted at its top surface under theline of seeming, as described, to prevent the heat from being conductedtoo rapidly from the can-seam to the cylinder, and thus producing animperfectjoint.

4. The combination, with the cocks ot" air and gas pipes, of the singleand double slotted bars M N and the hand-slide O, arranged to operate asand for the purpose described.

5. The air-pipe K. and three-Way cock- L- combined with burner,blow-pipes I g1, and cooling-pipe J, as and for the purpose set forth.
